A hole groove corresponding to the positioning shaft 7 is set at the installation location. Rotating the driving bolt 14 will cause the threaded barrel 13 to drive the position of the driving block 12 to move. When the driving block 12 moves, it will squeeze one side of the slider 6, thereby moving the slider 6, pushing the positioning shaft 7 to move, and moving the positioning shaft 7 to the outside through the hole 8. After the positioning shaft 7 moves into the hole groove set at the installation location, the positioner 5 is limited, and then the position of the anti-corrosion structure of the expansion joint of the desulfurization chimney is positioned and installed, so as to achieve the purpose of facilitating installation and improve work efficiency.
